Den foreliggende opfindelse angår en hovedramme til en betonstøbemaskine af den art, der anvendes til fremstilling af bloksten til pladsbelægning og vægopbygning.The present invention relates to a main frame for a concrete casting machine of the kind used for the manufacture of paving blocks for space paving and wall construction.

Med henvisning til Fig. 1 og fig. 2 beskrives hoveddelene i en betonstøbemaskine af 5 den angivne art.Referring to FIG. 1 and FIG. 2, the main parts of a concrete casting machine of 5 are described.

Hovedrammen (2) danner nederst basis for et vibrationsarrangement (3) på hvilket en produktionsplade (4) er anbragt, samt transportmidler (6) for transport af produktionsplader (4) igennem betonstøbemaskinen. Hovedrammen (2) danner endvidere basis for 10 et modholdsarrangement (8) for form-overparten (10), en betonsilo (12) samt det til støbemaskinen hørende fyldearrangement(14). Siderne og hovedrammen danner yderligere basis for søjlestyr (16) for parallel styring af formudstyret (18) og modholdet(8).The main frame (2) forms the base of a vibration arrangement (3) on which a production plate (4) is arranged, as well as transport means (6) for transporting production plates (4) through the concrete casting machine. The main frame (2) further forms the basis for a retaining arrangement (8) for the mold upper part (10), a concrete silo (12) and the filling arrangement (14) of the molding machine. The sides and the main frame form a further basis for column guide (16) for parallel control of the molding equipment (18) and the head restraint (8).

Vibrationsarrangementet, der omfatter et vibrationsbord (20) og et ristearrangement 15 (22), påvirker den overliggende produktionsplade (4) for komprimering af den beton der er fyldt i det nævnte formudstyr (18).The vibration arrangement, which comprises a vibration table (20) and a grating arrangement 15 (22), affects the overlying production plate (4) for compressing the concrete filled in said molding equipment (18).

Formudstyret (18) udgøres af en celledelt underpart (18) hvis celler (ikke vist) er åbne opefter og nedefter. Cellevæggene danner afgrænsningerne for og definerer den øn-20 skede grundform på den enkelte sten, og en modsvarende overpart (10) som fra en øvre holdeplade (24), monteret på modholdet (8), har nedadragende trykstempler (26), hvis undersider har tildannede trykplader (28), som passer ned i de respektive underliggende celler i underparten (18) og derved er brugbare til nedadgående modholdskraft, og til udskydning af støbeemneme fra cellerne.The molding equipment (18) is constituted by a cellular subpart (18) whose cells (not shown) are open up and down. The cell walls form the boundaries and define the desired basic shape of the individual stone, and a corresponding upper part (10) which, from an upper holding plate (24) mounted on the retainer (8), has downwardly projecting pistons (26) whose undersides have formed pressure plates (28) which fit into the respective underlying cells of the lower part (18) and are thus useful for downward restraining force and for pushing the moldings from the cells.

Under komprimeringsfasen, hvor vibrationssystemet (20,22) vibrerer produktionspladen (4) og formen (18) med betonen op mod de respektive trykplader (28), der virker som modhold for betonen i de respektive celler, udfoldes der en stor vibrerende kraft-påvirkning af hele hovedrammekonstruktionen (2), dels som reaktionskræfter fra vi-30 brationssystemet og dels som fastholdelseskraft af modholdssystemet (8) gennem toprammen (30), og siderne (32) ned til bunden. Søjlesfyrene (16) sikrer, at formens og modholdets bevægelser opad og nedad styres parallelt.During the compression phase, in which the vibration system (20, 22) vibrates the production plate (4) and the mold (18) with the concrete against the respective pressure plates (28) which act as a resistor to the concrete in the respective cells, a large vibrating force effect is felt. of the entire main frame structure (2), partly as reaction forces from the vibration system and partly as the retaining force of the restraint system (8) through the top frame (30), and the sides (32) down to the bottom. The column lids (16) ensure that the up and down movements of the mold and the backrest are controlled in parallel.

Bundrammen er normalt opbygget ved sammensvejsning af tilskåme standardprofiler 35 af typerne HEM, RHS, UNP, m.m., som det er vist i fig. 2. Standardprofileme skal, for at sikre en god svejsning, skærpes i en passende vinkel for at tillade en fuld gennem-svejsning af samlingen mellem de tværgående (34) og de langsgående (36) profiler.The bottom frame is usually constructed by welding together standard profiles 35 of the types HEM, RHS, UNP, etc., as shown in FIG. 2. To ensure good welding, the standard profiles must be sharpened at an appropriate angle to allow full welding of the joint between the transverse (34) and longitudinal (36) profiles.

Ved denne fremstillingsmåde optræder kræfterne fra komprimeringen typisk lige i, og 2 DK 174323 B1 omkring svejsezoneme (38). Kravene til materialer og svejsningerne ved fremstillingen af blindrammer af den angivne art er som det antydes, høje, hvilket skyldes at der ved svejsede konstruktioner der udsættes for vibrationer kun kan regnes med en styrke på 10-15% af grundmaterialernes styrke i svejsezoneme. Der vil således være betyde-5 lige ressourcer at spare ved fremstilling af en hovedramme til en blokstensmaskine, såfremt denne kunne fremstilles ved anvendelse af færre eller ingen svejsninger i de kritiske områder eller svejsninger i en lavere klasse.In this mode of manufacture, the forces of compression typically occur in and around the welding zones (38). The requirements for materials and welds in the manufacture of blind frames of the specified type are high, as indicated, because in welded structures subjected to vibration, only a strength of 10-15% of the strength of the basic materials in the welding zones can be counted. Thus, there would be significant resources to be saved in producing a main frame for a block machine if it could be produced using fewer or no welds in the critical areas or lower grade welds.

Det er ved opfindelsen indset, at det vil være muligt at fremstille en hovedramme af 10 den angivne art, som tillader anvendelse af betydeligt lavere klasser af svejsning, ved at fremstille hovedrammens bund af to flammeskåme plader der danner bundens grundfacon, hvilke bundplader er indbyrdes forbundne med i det mindste to langsgående og et antal tværgående kropplader.It is recognized by the invention that it will be possible to produce a main frame of the specified type which permits the use of significantly lower classes of welding, by producing the main frame bottom of two flame retardant plates forming the base shape of the base, which base plates are interconnected with at least two longitudinal and a plurality of transverse body plates.

15 Herved opnås det at der ikke forefindes svejsninger der belastes med vibrerende kræfter i sideretningen, samtidigt med, at svejsningerne mellem de flammeskåme plader og kropplademe uden reduktion af konstruktionens styrkemæssige forhold og kvalitet, kan reduceres til en betydeligt lavere svejseklasse, end den der benyttes ved fremstilling af de kendte hovedrammer.Hereby it is obtained that there are no welds loaded with vibrating forces in the lateral direction, while the welds between the flame-retardant sheets and the body sheets can be reduced to a considerably lower welding class without reducing the strength ratio and quality of the construction. manufacture of the known main frames.

20 I den hensigt yderligere at fjerne kræfterne fra komprimerings/vibreringsprocessen væk fra svejsezoneme, kan kropplademe med fordel være sammentappede, således at de tværgående plader er ført ud til kanten af over- og underpladerne gennem de langsgående kropplader og danner kropfoTstærkning til understøtning af henholdsvis over-25 og underplade, på samlingens udvendige side.In order to further remove the forces of the compression / vibration process away from the welding zones, the body sheets may advantageously be collapsed so that the transverse plates are extended to the edge of the upper and lower plates through the longitudinal body plates and provide body strengthening to support respectively -25 and lower plate, on the outside of the assembly.

Herved flyttes kræfterne fra komprimeringen væk fra svejsezoneme, idet svejsningerne nu er flyttet til et område, hvor der optræder mindre kræfter. I stedet overføres kræfterne nu fra vibrationssystemet til den resterende del af hovedrammen via områ-30 der der ikke omfatter svejsninger, og til fundamentet via områder der ikke omfatter kritiske svejsninger. Flytningen af kræfterne bort fra svejsezoneme har tillige en væsentlig, og positiv indflydelse på konstruktionens levetid, og som allerede nævnt på mulighederne for reduktion af såvel mængde af, som svejseklassen der skal benyttes i konstruktionen, for opnåelse af en acceptabel levetid for denne.This forces the forces from the compression away from the welding zones, since the welds have now been moved to an area where less forces occur. Instead, the forces are now transferred from the vibration system to the remaining portion of the main frame via areas that do not include welds, and to the foundation via areas that do not include critical welds. The relocation of the forces away from the welding zones also has a significant and positive influence on the life of the construction, and as already mentioned on the possibilities of reducing both the amount and the welding class to be used in the construction, in order to obtain an acceptable life for it.

Det skal endvidere anføres, at toppen af blokstensmaskinens hovedramme ligeledes kan udføres af to flammeskåme plader, der er indbyrdes forbundne ved et passende antal langsgående og tværgående kropplader.Furthermore, it should be noted that the top of the block stone main frame can also be made of two flame guard plates which are interconnected by an appropriate number of longitudinal and transverse body plates.

Opfindelsen forklares nærmere i det følgende med henvisning til tegningen, hvor fig. I er et perspektivbillede af en betonstøbemaskine med en hovedramme ifølge op-5 findelsen, fig. 2 er et sidebillede af den i fig. I viste betonstøbemaskine, fig. 3 er et perspektivbillede af en hovedrammeopbygning til en betonstøbemaskine ifølge den kendte teknik, fig. 4 er et eksploderet billede af bunden af en hovedramme ifølge opfindelsen, 10 fig. 5 er det samme som fig. 4, men hvor bunden af hovedrammen er samlet, og fig. 6 er et perspektivbillede af en hovedrammeopbygning med en bund ifølge fig. 5.The invention is explained in more detail below with reference to the drawing, in which fig. 1 is a perspective view of a concrete casting machine with a main frame according to the invention; 2 is a side view of the embodiment of FIG. In the concrete casting machine shown in FIG. Figure 3 is a perspective view of a main frame structure for a prior art concrete casting machine; 4 is an exploded view of the bottom of a main frame according to the invention; FIG. 5 is the same as FIG. 4, but where the bottom of the main frame is assembled, and fig. 6 is a perspective view of a main frame structure having a bottom according to FIG. 5th

Fig. 4 er et eksploderet billede af bunden 40 af en hovedramme 2 ifølge opfindelsen til en betonstøbemaskine. Som det fremgår udgøres bunden 40 af to flammeskåme pla-15 der 42, 44, to langsgående kropstykker 46, 48, samt tre tværgående kropstykker 50, 52, 54.1 fig. 5 er den i fig. 4 viste bund 40 af hovedrammen 2 vist i sammensvejst tilstand.FIG. 4 is an exploded view of the bottom 40 of a main frame 2 according to the invention for a concrete casting machine. As can be seen, the bottom 40 is comprised of two flame shield plates 42, 44, two longitudinal body pieces 46, 48, and three transverse body pieces 50, 52, 54.1 FIG. 5 is that of FIG. 4 shows the bottom 40 of the main frame 2 shown in welded state.

I fig. 6 er hele hovedrammen 2, med bund 40 ifølge den foreliggende opfindelse vist i 20 perspektiv. Det skal bemærkes, at overrammen 30 kan være opbygget efter samme princip som bunden 40.In FIG. 6, the entire main frame 2, with bottom 40 of the present invention, is shown in perspective. It should be noted that the top frame 30 may be constructed according to the same principle as the bottom 40.

Fordelen ved denne opbygning af bunden 40 af hovedrammen 2 er, at de kræfter der overføres fra vibrationsarrangementet 3 til bunden 40, ikke overføres på tværs af 25 sammensvejsninger, hvilket medfører at der ved samlingen imellem de flammeskåme plader 42, 44, og kropstykkeme 50, 52, 54 kan benyttes svejsninger i lavere klasser og i betydeligt mindre omfang end ved den samlemetode, der normalt benyttes ved fremstilling af hovedrammer, som angivet i fig. 3, hvor nævnte kræfter mellem de tværgående profiler 34 og de langsgående profiler 36 overføres via svejsningerne 38.The advantage of this construction of the bottom 40 of the main frame 2 is that the forces transmitted from the vibration arrangement 3 to the bottom 40 are not transmitted across 25 welds, which means that at the joint between the flame retardant plates 42, 44 and the body pieces 50, 52, 54, welds can be used in lower classes and to a much lesser extent than in the assembly method normally used in the manufacture of main frames, as shown in FIG. 3, wherein said forces between the transverse profiles 34 and the longitudinal profiles 36 are transmitted via the welds 38.

Der er således ved hovedrammen til en betonstøbemaskine ifølge opfindelsen angivet en opbygning, der udover at frembyde samme eller længere levetid som den kendte hovedrammekonstruktion, er betydeligt billigere at fremstille, idet de svejsninger der kan benyttes ved konstruktion af bunden 40 ikke stiller samme krav til skærpning af 35 svejseflademe, ligesom svejsningen i øvrigt kan udføres i lavere klasse, hvilket medfører mulighed for at fremstille en betonstøbemaskine til en mere konkurrencedygtig pris.Thus, in the main frame of a concrete casting machine according to the invention, a structure which, in addition to offering the same or longer life as the known main frame structure, is considerably cheaper to manufacture, since the welds which can be used in the construction of the bottom 40 do not impose the same requirements for sharpening. of the 35 welding surfaces, just as the welding can otherwise be carried out in the lower class, which makes it possible to manufacture a concrete casting machine at a more competitive price.
